The students in Ms. Meisner’'s art class are designing a large stained-glass window for the school. The window will be 2 meters tall and 5 meters wide. This is the design for the window: The colored glass costs 200 baht per square meter, and the clear glass costs 100 baht per square meter.
How much will the students need to spend for the glass?

answer: i don't understand. what are the options

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
